Publication number: 20200188058Abstract: A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument.Type: ApplicationFiled: December 13, 2018Publication date: June 18, 2020Inventor: Mario Mata

Publication number: 20200188099Abstract: An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can have a first set of a plurality of struts extending in a first direction, and a second set of a plurality of struts extending in a second direction, and each strut of the first set of struts can be pivotably connected to at least one strut of the second set of struts. Each strut can be curved helically with respect to a first, longitudinal axis of the frame, and each strut can be curved with respect to a second axis that is perpendicular to the first, longitudinal axis of the frame.Type: ApplicationFiled: February 11, 2020Publication date: June 18, 2020Applicant: Edwards Lifesciences CorporationInventors: Anatoly Dvorsky, Tamir S.

Publication number: 20200188100Abstract: A prosthetic heart valve can include an outer frame coupled to an inner frame such that the outer frame can be moved between a first position and a second position in which the outer frame is inverted relative to the inner frame. The inner frame and the outer frame define between them an annular space, and a pocket closure can bound the annular space to form a pocket in which thrombus can form and be retained. The pocket closure can include a stretchable pocket covering that can move from a first position in which the pocket covering has a first length when the outer frame is in the first position relative to the inner frame and a second position in which the pocket covering has a second length greater than the first length when the outer frame is in the second position relative to the inner frame.Type: ApplicationFiled: February 21, 2020Publication date: June 18, 2020Applicant: Tendyne Holdings, Inc.Inventors: Zach Vidlund, Michael Evans, Robert M.

Publication number: 20200188101Abstract: A device for providing cardiac treatment at the left atrium of a patient's heart. The device includes a retention body and a prosthetic valve. The retention body has a shape that can be manipulated between a collapsed state and a normal or expanded state. First and second openings are defined at one side of the retention body, and a lower opening is defined at an opposite side. The prosthetic valve is carried by the retention body at the lower opening. The retention body is configured to engage a substantial portion of an interior surface of the left atrium, securing the prosthetic valve at a desired location relative to a native mitral valve (e.g., within the mitral valve or slightly spaced from the mitral valve). The first and second openings are sized and shaped so as to permit blood flow from the pulmonary veins into the interior region.Type: ApplicationFiled: February 25, 2020Publication date: June 18, 2020Inventor: Jeffrey W. Chambers
